We're sure that many Xbox fans have been trying out MW3 over the past few days - even if just for curiosity's sake - so we're keen to hear what you think about it so far! We didn't give it the best rating back in November of last year, but to be fair it's added quite a lot of free new content since then.
The main course properly arrives this November when Call of Duty: Black Ops 6 launches day one on Xbox Game Pass, so Microsoft will be hoping that Modern Warfare 3's arrival is enticing a bunch of new and returning players.
But has it enticed you yet? Let us know what you think about Call of Duty: MW3 down in the poll and comments below, as well as whether you're eagerly anticipating the arrival of Call of Duty: Black Ops 6 later this year.
